Kei Nishikori came from behind to beat Gael Monfils at the Miami Open and the Japanese star is not entirely sure how he did it.
The number six seed saved five match points and advanced to the semi-finals after two-and-a-half grueling hours of play.
Speaking afterwards, Nishikori admitted that he thought the game was lost at a stage.
“When I was down 4-5, love-40, I thought it was going to be it,” Nishikori said.
“It was going to be tough to come back. I tried to play one point at time.
“I saw that he was down a little bit in the tie-break, so I tried to be focused. I did pretty well in the tie-break.”
Despite beating him, Nishikori was full of praise for Monfils and his approach to the game.
“I enjoy how he plays,” Nishikori said.
“You don’t see many other players who play that way.
“He’s a very athletic player and gets to every ball, so it’s not easy to play him.”
